Of course it came from some where - it had to be contained, at the molecular level - in other words the instructions to make the wing bigger, or longer or more "feathery" - HAD to come from somewhere

you already understand the mutation process and the origins of variation within populations

you can answer your own question

DNA replicates itself

the variation is a result of that replication process
